Lead poisoning results in permanent neurological damage resulting in learning and behavioral problems. The sad thing it is preventable. There are numerous source of lead: in our soil, air, drinking water, and homes. There is over 3 million tons of lead in 60 million American homes. It is found on watercoolers at school, windowsills, in the dirt in yards, seals of fine wine, lead crystal glasses, dishes, coffee mugs, crayons, on toys, and even in calcium supplements. Homes built before 1976 contain some lead in their tap water because of solid lead pipes or lead soldered copper pipes.
Children absorb 50% while parents only 10%. Children pick up lead dust from floors, pets, and toys and then suck their thumbs. The lead compound on paints taste sweet. Lead is stored in baby's teeth and their kneecaps. Lead finds to the red blood cell like iron and is stored like calcium in the teeth. When there is a deficiency of protein, phosphorus, iron, or calcium, more lead is absorbed.
Hobbies like soldering and melting lead is a great source of lead poisoning. Burning colored newsprint or wood coated with lead paint, results in a release of lead into the air. Lead gasoline, phased out in 1976, was also a great source. Storage, preparation and serving of foods are another source. Juices from containers that come from lead soldered cans can leak the acids into the juice and be absorbed.
Pigmented designs on pottery dishes and mugs are glazed with lead to make them washable. The glaze contains deadly cadmium. This lead can be absorbed when hot food is served on them. Leaking is increased by acidic food as coffee, pop, fruit juices, or alcohol, combined with the decorative glaze and lead pigment.
In 1990, 90 % of all canned food was packaged in lead soldered cans (98%lead and 2% tin; lead is 10% the cost of tin.). Note that soldered seams are raised and lumpy with gray metal while welded seams are soft, smooth and flat.
Wine formerly had corks sealed with hot wax and lead foil wrapped around it. The lead went into the wine. Place the wine in fine crystal and you also have immediate absorption of lead also from the crystal directly into the wine.
Calcium pills are made from bone meal and oyster shells (sources of lead). Best to choose calcium carbonate or antacids for your source of calcium.
Brass bowls contain 3% lead. Pewter is made from tin and lead. Silver plates contain often an alloy of lead. Newspapers with colored print contain lead. (So don't wrap your fish in the comics.) Water coolers had lead lined storage tanks until 1988. Sandblasting of old bridges releases a large amount of lead.
Pregnant moms absorb more that non-pregnant woman. The average lead levels were 17 micrograms per cc in 1976 and today are 4 micrograms. In 1965 the levels were 60 and dropped down in 1985 to 30 and by 1990 to 10 micrograms.
